The 3D printed bumper is fairly easy to make with most common FDM style 3D printers that on the market.


And if you don’t have access a 3D printer, you can order our parts by visiting our Thingiverse page and have a local maker 3D print the parts and ship them to you.

This bumper is specifically designed for flexible material only! It will not fit the device if printed in hard plastic!

Slice Settings

Download the STL file and import it into your 3D printing slicing software. You'll need to adjust your settings accordingly if you're using material different than PLA.

CURA 3.X Slice Settings

  • 225C Extruder Temp
  • 60C for heated
  • .4mm Nozzle
  • 0.38 Line Width
  • 2 shell count
  • .2mm Layer Height
  • 10% infill
  • Support Material On
  • 25mm/s default print speed
  • 8mm retraction distance (bowden)

Flexible Filament


TPU (thermoplastic polyurethane) filament is a flexible material that's ideal for gaskets, plugs, leveling feet, and mobile device cases!


There's different types of TPU, some which more elasticity than others and others with more grip. 


Bed Adhesion


60C temperatures for heated beds. For non-heated beds, PEI sheet and blue tape works well.

3D Printer & Slice Setting


Follow your printers recommended settings below for a good starting point. 


Print Hotter

TPU extrudes best at 220C-225C temperatures. It has a higher melting point and requires more heat than regular PLA.

Clean up


We used a flush diagonal cutters to clean up support material around the inner edges. 


Make sure the openings for the mute switch and USB-C ports are cleaned before plugging in cable. Use a hobby knife to help cut away stringing that could block the volume switch.
